TRS: Techmino Rotation System, a rotation system used in Techmino based on SRS. TRS added some extra useful wall kicks and fixed the problem with S and Z tetrominoes getting stuck on certain terrains. It also added wall kick tables for pentominoes based on the wall kicks for tetrominoes.
TRS supports O-spins, where the O tetrominoes can be transformed into other tetrominoes or teleported into holes by pressing certain keys or buttons.
